Nadia’s page has three sections and has never exceeded one side: what changed, what she wants to decide, and what she is worried about. She writes it the night before and does not send it in advance.
Emailing it means it might get read. Putting it on the desk means it is in the room.
The effect she describes is about visibility rather than content. A written list makes the remaining items countable, which converts the end of an appointment from a drift into a choice somebody has to make out loud.
